New varieties of fruit trees and ornamental plants created through painstaking work are being illegally cultivated and marketed at low prices—a serious problem that infringes on breeders’ rights. To enable the identification of different varieties and prevent illegal cultivation, a broad range of research and development at the DNA level has been conducted so far. In the case of fruit trees and ornamental plants propagated by grafting or cuttings, however, no useful method of identification has been established because new varieties and their parents often share the same DNA. Against this background, the DNA marking technique developed by Tomoki Matsuyama, Research Unit Leader in the Plant Breeding and Cell Engineering Research Unit at the RIKEN Advanced Science Institute, is drawing attention as a solution to the recently emerging issues concerning food safety, such as deceptive labeling of production centers.
